Sargent 82-0370 Genuine OEM Replacement Spindle for 8200 & 7800 Series Mortise Locks

The Sargent 82-0370 is a genuine OEM replacement spindle designed for Sargent 8200 Series and 7800 Series mortise locks. Sourced directly from Sargent, this spindle ensures a precise, factory-correct fit — restoring proper lever or knob operation without modification or improvised workarounds. When a mortise lock spindle wears, breaks, or goes missing during service, substituting a non-OEM part risks misalignment and premature failure; the 82-0370 eliminates that risk entirely.
